For the purpose of laying lines and of maintaining the same in repairthe .trackmen are supplied with'rules o-fwoocl or of iron or with.special, forms permittingiof testing" either thegauge of the, tracksortheir level in alignmentor their cant in the curves These lnstrument's"are cumbersome and heavy to carry outside the workshops, and

they can be used onlyby the surveyorsand controller's of the tracks thebusiness of whom is, to examine the state of the tracks n order topreventthe j accidents which might be tuber caused by widenings orslackings, deformations or getting out of level of the tracks Theinstrument according to thls 1nvention andwhich has the fol-mend thedimensions of awalk'ing stick is 'oflight weight,

easy to carry andpe'rmits the surveyors to testand verify in the courseof their 'visits'any ange of the track and its level as well as the cantin the curves.

In the inoperative position the inner tube 5 issecurely fixed-in theouter tubes, for instance by means'of a ring 10, roughened on the outersurface and carrying a bolt 11 adapted to engage with two bayonetgrooves 12, 12 in the end ofthe-inner tube 5. Two transverse cavities13,13 in the outer tube 4 allowthe boltll to pass and the ring 10 tocarry out the part rotation necessary to bring said bolt 11 inengagement with the transverse'parts of the slots 12, 12 of the innertube 5." Q :1 p I 1 A flap 14: hingedly mounted at 15 on the inner tubeAnear the end of'the same is accommodated in the inoperative position insaid tube, which is accordingly indented, and it can be turned to theouter side to stand perpendicularly to saidtube in the same plane andatthe same side as the handle 3, the amountof turning of said flap 14being limited to 90 by a suitable stop.

A gra'duation 16 from 1,480 meters to 0.875

meters, engraved .onthe inner tube 5 completely developedand startingfrom the end A cane-1ferrule?I7 is fixed by means of'a V screw on theouter'end of the inner tube 5. The thickened"porti0n17a' of this ferruleis milled to facilitate pulling the inner tube tive position in thehandlebut adapted to be turned 90 around. an'aX'le an'dit can be placedthen .onadistance Of1100 f-mms,

which corresponds to the length of the handle, different. perpendicularpositions to said handle from the position a to the position bi'ndio'a-ted .inFig. 11*. A graduation 21 is engraved on the handle(.the graduation being shown for clearness-salie in Fig. IIat the sideof the handle) ,lthe zero registering very accurately with the innersurface of tube 5. The rule 19 might bezextended from the handle inalignment of the same a distance of 100 IIlIl'lS. into the position a. i

The rule 19 carries, preferably at its upper part and near the tail, asmall Ifl-ap ,32which is hinged-1y mounted. In the inoperative statethis flap (position 32a.Fig. 11)"prevents displacing of the rule: 19an-dit covers the hollow space existing above the rounded portion of'thetail of this rule. Oscillated about 90' it assists in the longitudinaldisplacementof said rule. 7

"The section in the'form. of-an inverted L, preferably given to thisrule, permits its flap, in order to limit the rotation, to; abut againstthe upper rabbetof the part 3a,-i; e. against the face of this partwhich isgraduatedfrom 0 tolOO inms. graduation 2'1) and: furthertoprevent saidirule-from turning with regard to the handle to an anglegreater than 90.".

The rule 19 in .the' inoperative position forms an integral partofthehandle 3, and

. its flap hides said graduation 21. Thisrule is graduated itselfon oneof its side faces from 100 mms. (lower part) to 20.0 min-s. (aipper partthe reading being donefrom the position b to the position: 0 towards theend of the handle.

The axle 20 on which tworollers 22 are mounted permits of the head ofthe rule rothe handle arecon sequently indented at 23, 23

for accommodatingsaid rollers 22-. The movement of. the rule-'19 tothe-different positions which it may assume is effected tion theform. ofaninvertedL, might besimplyfla-t, theflapraabeingsuppressed.

In this case the upper rabbet'of the handle is also suppressed and inorder that the rotation of the rule around its axle be limited andtherule be maintained open in the normal position with regard to the handlefor testing the level and the cant comprised between .0 and 100 mms. itstail, instead of being rounded in semicircle, would be rounded only aquarter of a circle, the other portion being out atright angle in orderthat the shoulder thus formed will abut in the open position of. therule against the bottom of the corresponding cavity of the handle.Thegraduation which in the first form of construction described wasprovided in the rab'het ofathe handleis in this form of constructionmarked directly on the upper face of one of the parts of the handle. v

The control cane according to the inventionisused in the followingmanner.

, V Totestthe gauge of tracks (Fig. 12) the inner tube 5is pulled outpartly and the end flap 14 is oscillated into a position perpendicularto. said tube .5.

. The handle end of the caneis then placed outer. tube 4 the registeringgraduation 10f" the inner tube indicates the accurategauge of thetrack-at the part in question.

(7)) To test the level of the track (Fig. 13) the inner tube is: pulledout completely the flap 14? being not open. The rule 19 of the handle isbrought into the position perpendicular to the handle, care having tobetaken that its lower face registers accurately with the zero of thegraduation 21- of the handle. The cane is then placed'on the rails sothat the vertical handle 3 abuts against theinner edge of the-headof oneof. the rails,- for instance rail 25, the rule 19- resting on the upperface of said rail and the other end ofthecane resting upon the upperface of the other rail 26-, the whole apparatus being placed normally tothe axis of the track. If the track is level, the air bubble of thelevel 9 is standing at the centre of the aperture 8 of the cane.

(0). To test the cant or super-elevation of the track inthe curves, whenthe same is comprised between zero andlOO mms. (Fig. 13),

the cane, the rule 19 of'which is completely I 7 open and the inner tube5is completely pulled out, i. I e. similar to the testing of level, isplaced on the rail so that the rule 19', as indicated in dash dot lines,rests on the upper face of rail 27 of the lower line, the otherend ofthe cane resting on the upper surface of the'other rail 26,whereupon'the rule--19 is displaced parallel toitself from the positiona intozthe. p sition. 11 unt l. he; bub le level 9 indicates thehorizontal position. On the graduation 21 on the handle of the cane thedlvision line registering with the lower edge of rule 19 indicates thesuper-elevation of the 7 high line of the track with regard to the lowline of the same. 7 r

(d) For testing the cant, when it is comprised between 100 and 200 mms.(Fig. 14),

the cane is placed in a position similar to that described under 0, therule 19 resting however in the handle and its endbearing onthe centre ofthe upper face of rail 28 of the low line.

The rule 19 is then shifted'in the longitudinal direction in the handletowards the position 0 by lifting the handle 3. When the bubble level 9of the cane indicatesthe horizontal position, the division line on thegraduation 29 of rule 19, corresponding to the end of the handle,indicates the cant of the track.

The different elements of this cane are preferably made of aluminum, inorder to reduce the weight. o

Besides the essential and most direct applications which have beendescribed, the cane according to the invention might be used also fortesting the inclinations of the rails, gradients of the track (profilein longitudinal direction) and the parallelism of the wheels of vehicles(wagons or locomotives) said parallellism having frequently to be,verified after derailments.

When the cane according to the invention has to be used for testingelectrified tracks, comprising insulated rails or having theelectricblock, the handle of this cane will be made of a special wood so that nodeviations of the electric current can be caused.

I' claim A control cane for testing gauges of railway tracks, the leveland the cant of the same, comprising in combination a tubular stick, atube telescoped into said tubular stick and graduated along one side, abubble level in said inner tube, a handle fixed in the end of saidtubular stick in an accurately'perpendicular direction having agraduation, the

zero of which registers very accurately with the inner surface of saidinner tube, said handle having inner grooves, a graduated rule in saidhandle, lateral rollers on said rule adapted to slide in said innergrooves of said handle, and an-aXle on which said rollers are mountedand around which said graduated rule can turn its upper extreme positionbeing such that its lower edge registers with the said inner surface ofsaid inner tube.

In testimony whereof I afiix my signature.
